PIPE -CLOSURE Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed July 19,1906. Serial No. 326,859.

To all whom it may concern:

Be it known that I, ALFRED AmioNT FISK, a citizen of the United States,and a resident of Pomona, in the county of Los Angeles and State ofCalifornia, have invented a new and Improved Pipe-Closure, of which thefollowing is a full, clear, and exact description.

The invention relates to irrigation pipes, stand pipes and the like, andits object is to provide a new and improved pipe closure arranged topermit of conveniently, quickly and securely closing the end of a pipe,andto allow of opening the same for making connection with another pipewhenever it is desired to do so.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawing forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement; Fig. 2 is a transversesection of the same on the line 22 of Fig. 1, and Fig. 3 is a sectionalplan view of the same on the line 33 of Fig. 2.

On the irrigation pipe, stand pipe or other pipe are arranged trunnionsB located diametrically opposite each other and having shanks B fastenedby rivets B or like devices to the sides of the pipe A a distance fromthe terminal thereof. The trunnions B are engaged by the side arms C ofa bail having its middle portion 0 extending beyond the terminal of thepipe A, and in the said middle portion 0 of the bail 0 screws a screwrod D engaging a cross head E mounted to slide on the side arms 0 of thebail C. To the cross head E is secured a wooden disk valve F, having itsunder side preferably concave, and adapted to be seated on the terminalof the pipe A so as to close the same to prevent the escape of water orother liquid passing through the pipe. One side of the disk valve F isprovided with a semicircular depending flange G adapted to engage thecorresponding side of the pipe A, and the side arms C of the bail G areprovided with a semicircular guard H likewise adapted to rest againstthe side of the pipe A to limit the swinging motion of the bail C. Now,when it is desired to connect another pipe to the pipe A, it is onlynecessary for the operator to unscrew the screw rod D so as to cause thecross head E to slide outwardly on the slide arms G of the bail O, andas the disk valve is secured to this cross head E, it is evident thatthe disk valve moves with the cross head and away from the terminal ofthe pipe A. When this takes place the bail C can be swung downward intothe position shown in dotted lines in Fig. 1, so that the pipe A is openand completely free at its terminal, to permit of connecting anotherpipe to the terminal of the pipe A.

A flange G serves to prevent water flowing out of the pipe and ofsquirting onto the operator when plac- 'ing the valve F in a closedposition, that is by swinging the bail upward, to bring the disk valve Fover the terminal of the pipe A, and to then move the disk valve Fdownward by screwing the screw rod A inward until the under face of thedisk valve F is seated on the end of the pipe A.

The device is very simple and durable in construction and can be readilymanipulated for closing the end of the pipe or for opening the samewhenever it is desired to connect another pipe with it.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

1. A closure for irrigation pipes, stand pipes, and like pipes,comprising a bail hinged to the pipe, a screw rod screwing in the bail,and a valve held on the said screw rod and adapted to be seated on theend of the said pipe said valve having a semi-circular depending flangeat one of the sides thereof.

2. A closure for irrigation pipes, stand pipes and like pipes,comprising a bail hinged to the pipe, a screw rod screwing in the bail,a wooden disk valve having a concave face and held on and running bodilywith the said screw red, the said concave face being adapted to beseated on the end of the said pipe, and a semicircular flange dependingfrom the said disk valve.

3. A closure for pipes, comprising a bail hinged to the pipe, a rodthreaded through the bail, a valve held on the said rod and adapted tobe seated on the end of the said pipe, said valve having a semi-circulardepending flange at one of the sides thereof, and a semi-circular guardconnected with the arms of the bail and adapted to engage the pipe whenthe said valve is swung into place.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
